Research Interests

The multi-disciplinary research programs in the Fang Group will focus on the bottom-up synthesis and processing of novel organic polymer materials — namely, ladder and coplanar polymers, as well as microporous polymer networks — for the applications on electronics and energy conversion/storage. Our thrust will be to gain profound understanding on the structure-property relationship of these materials at both the molecular and the macroscopic levels by employing the toolboxes of synthetic chemistry and device engineering. With this knowledge, we aim to establish a series of synthetically feasible, high performing, processable organic carbon-based material systems for field effect transistors, light emitting diodes, solar cells, supercapacitors, and batteries, and to be at the forefront in the enhancement of their efficiencies.
